Anycubic Mega Zero Z-Axis Linear Rail

**EDIT**:

- Added flexure lead screw bearing block alternative to the remixed bearing block. The flexure design allows room for the leadscrew tip to wobble and hopefully prevent the deflection force from translating into the x-gantry and cause z-banding patterns.

**End EDIT**


This mod swaps v-wheels for linear rails and supports dual lead screws. The lead screw mounts also feature a flexure design to help mitigate z-banding (modified from a design by [@amtech](https://www.thingiverse.com/amtech/designs) [https://www.thingiverse.com/thing:4806806](https://www.thingiverse.com/thing:4806806)

The mounting plate was remixed from https://www.thingiverse.com/thing:4804383 by @djos_1475.

I assume that you are currently using dual lead screws already and if you are not then you will need to procure a secondary leadscrew and motor as well as research hot to connect the secondary motor. I am currently using an SKR Mini MZ and it supports 2 z-axis motors connected in
